      mw[mi][i] is the mi (mi=1 to wav[i])  effective wave of individual i               minus probability to die before dh-stepm . 
      dh[m][i] of dh[mw[mi][i][i] is the delay between two effective waves m=mw[mi][i]               In version up to 0.92 likelihood was computed
      and mw[mi+1][i]. dh depends on stepm.          as if date of death was unknown. Death was treated as any other
      */          health state: the date of the interview describes the actual state
           and not the date of a change in health state. The former idea was
   int i, mi, m;          to consider that at each interview the state was recorded
   /* int j, k=0,jk, ju, jl,jmin=1e+5, jmax=-1;          (healthy, disable or death) and IMaCh was corrected; but when we
      double sum=0., jmean=0.;*/          introduced the exact date of death then we should have modified
           the contribution of an exact death to the likelihood. This new
   int j, k=0,jk, ju, jl;          contribution is smaller and very dependent of the step unit
   double sum=0.;          stepm. It is no more the probability to die between last interview
   jmin=1e+5;          and month of death but the probability to survive from last
   jmax=-1;          interview up to one month before death multiplied by the
   jmean=0.;          probability to die within a month. Thanks to Chris
